KB055CP0 Bearing Product Overview & Core Advantages
The KB055CP0 is a thin-section open bearing designed for applications demanding space optimization without compromising performance. As part of the Reali-Slim Open Bearings series, this single-row ball bearing is engineered to provide high precision and reliable operation in radial load applications. Its inch-series construction ensures a compact cross-section, making it ideal for machinery where weight and space are critical constraints. Manufactured to ABEC-1 tolerance standards, it offers consistent performance and is pre-lubricated for immediate use, supporting a broad operating temperature range.
KB055CP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KB | Indicates the Reali-Slim® series, thin-section bearing family. |
| 055 | Specifies the bore diameter in inches (5.5"). |
| C | Denotes the cross-section size/type within the Reali-Slim series. |
| P | Indicates an ABEC-1 Precision tolerance class. |
| 0 | Specifies an Open (unsealed) configuration. |
KB055CP0 Bearing Structural Features & Performance Benefits
This bearing's performance stems from its optimized thin-section design and material selection:
- High Rigidity & Space Savings: The single-row construction with a minimal cross-section (0.3125" width) provides high radial stiffness while dramatically reducing envelope size and weight (0.41 lbs), crucial for compact machinery.
- Radial Load Capacity: Engineered specifically for radial loads, it offers a dynamic load rating of 984 lbf and a static load rating of 2360 lbf, ensuring durability under operational stresses.
- Precision & Smooth Operation: The ABEC-1 tolerance class and brass cage contribute to smooth, low-vibration rotation and consistent performance. The tight radial internal clearance (0.0000 – 0.0005") allows for precise shaft positioning.
- Material Durability: Components made from Chrome Steel (rings and balls) provide high wear resistance and longevity, suitable for the specified temperature range of -30°C to 110°C.
KB055CP0 Bearing Typical Application Areas
The KB055CP0 is ideally suited for applications requiring large bores with minimal cross-sections, including:
- Robotics: Joint and actuator bearings in robotic arms.
- Aerospace & Defense: Gimbals, control mechanisms, and radar systems.
- Medical Equipment: Scanning and imaging devices.
- Semiconductor Manufacturing: Precision stages and handling equipment.
- Optical Instrumentation: Rotary stages and positioning systems.
